Bought this super cheap foam 3d plane kit for $8.50 including shipping (not in USA).
No instructions for build but seems obvious. 2206 motor but don't know size of lipo. I will try 800mah 3s as that is all I have but may be too heavy as
this is 58cm wingspan. At least I can use as template on some EPP foam I have when I destroy it. Bought it to learn 3d flying.

Update: this was an awful kit. Did not fly well and disintigrated almost immediately.
Building a scratchbuilt Bug now with EPP foam.

It seems the little brother of this:

so I presume you could use same instructions for assembling (you can download them from the file section) but I would suggest a smaller motor and a 2s 500mAh battery

Thanks. I found this English version after you showed me the Italian one. It doesn't make complete sense but I don't see any problems. Surprising the 850mm version takes such a range of batteries and motor sizes. I may have to buy smaller battery but will try what I have and see if it flies.

It will fly anyway, but pay attention to the flying weight : I fly rc model since 1968 and in all this years I have seen very few light model fly bad, but heavy one fly good none.
